NITED STATES OTTO SOHIMANSKY, OF SANDUSKY, OHIO, ASSIGNOR OF ONE-HALF, BY MESNE ASSIGNMENTS, TO D. J. BROWVN, OF SAME PLACE.

MACHINE FOR POINTING HOOPS.

SPECIFICATION forming part of Letters Patent No. 393,124, dated November 20, 1888.

Application filed December 19, 1887. Serial No. 258,271. (No model.)

To all whom it may concern Be it known that I, OTTO SOHIMANSKY, a

, citizen of the United States, residing at Sandusky, in the county of Erie and State of Ohio, have invented certain new and useful Improvements in MachinesforPointing Hoops, of which the following is a specification, reference being had therein to the accompanying draw- 1ngs.

This invention relates to new and useful improvements in machines for pointing hoops; and the invention consists in the peculiar construction and arrangement of the parts, as more fully hereinafter described, and specifically pointed out in the claims.

In thedrawings which accompany this specification, Figure 1 is a side elevation of my machine as arranged for operation. Fig. 2 is a detached perspective view of the lower portion of the machine, and Fig. 3 is a horizontal section through the knife head and knifeguides on the line w 00 in Fig. 1.

Aistheframe ofthe machiue,which supports the operating parts, and this frame consists, substantially, of two parallel uprights, R S, connected by cross-girts T, and provided with suitable flanges, U, for securing the frame by bolts or otherwise, as shown, to the post B at a suitable distance above the floor, whereby no floor-space is taken up by my machine, which is a great advantage of my machine. Between the upper ends of the uprights of the frame I journal the shaft 0, upon which is se-.

cured the drive-pulley D and the crank-disk E.

F is a knife-head provided with the vertical shank G,which reciprocatesin suitable guides, H, projecting from the frame.

I is a connecting-rod by means of which reciprocating motion is imparted to the knifehead.

The knife-head F is wedge-shaped in crosssection, as shown, and has adj ustably secured to it the knives J, the cutting-edges of which are made on an incline to obtain a shearing cut.

K and K are guides secured to the frame and projecting in front and rear of the knifehead to guide the same in its operation, and L is a stop secured to the rear guide and projecting downwardly.

M is a cutting-block firmly secured to the frame of the machine, and provided with the hoop-rest N, and. the centering hoop-guides O and P detachably secured in position. These guides are curved outwardly at their upper ends, which construction facilitates the insertion of the hoops, as will be readily understood.

In practice the operator stands in line with the hoop-rest N, or nearly so, which enables him at a proper moment when the knife is Withdrawn to chuck the end of the hoop, or rather of a number of hoops, under the reciprocating knife, so that the hoops rest upon the cutting-block and impinge with their free ends against the stop L. The knife in descending then points all the hoops at once with a shearing cut. I enable the operator to place a whole handful of hoops in the pointing-machine at once, as the centering-guides O and P and the stop L will enable him to adjust them all in line upon the cutting-block, and with a little experience on the part of the operator theknife may be reciprocated at quite a considerable speed without the least difficulty in chucking the hoops under the knives at the proper moment when the knife is withdrawn. Now, as is well known, the usual hoop-cutting machines operate upon a plank and cut it up in a number of hoops at the same time. If my machine is placed near such a machine the operator may at once grasp the whole number of hoops as they come from the cutting-machine,and transfer them to my pointing-machine, thus performing the pointing without the employment of extra labor.

In this connection the advantage of the construction of the frame of my machine will be readily understood. As I do not need any floor space, I am enabled to secure it anywhere that is most convenient for the operator, and all the dbris can be readily carried ofi withoutinterfering with the operator or with the operation of the machine.

To release the hoops after they are cut more freely from the knives, I relieve the inner faces of the knivesa little distance above the cutting-point, as shown in the drawings,where a are shoulders formed upon the inner faces of the knives, above which the knives are relieved.

Aside from guiding the knife-head the front guide,K,also acts as a stripper, as the knife in withdrawing, if it should happen to carry the hoops up, will carry them against the under side of the guide K and thereby force them out.

The guides O and P are removably secured for the purpose of securing different guides for different sizes of hoops, or to cut the points at different angles.

What I claim as my invention is- 1. In a hoop-pointing machine, the combination, with the cutting-block and the reciprocating knife-head and knives, of the hooprest on the cutting-block in line with the knives, the stationary stop at the rear of the knives, and the hoop-centering guides O I on the hoop-rest, and provided with outwardly curved upper ends, substantially as described.

2. In a hoop-pointing machine, the combination, with the cutting-block, of the reciprocating knife-head carrying the knives, the knife-guide K arranged back of said knives,

and the combined knife-guide and stripper K in front of the knives transversely of the hoops, substantially as described.

3. In a hoop-pointing machine, the combination of the frame A, the shaft 0, the drivepulley D, the crank E, the connecting-rod I, the reciprocating shank G, connected to the crank E by said rod, the knife-head F, carried by said shank, the knives J on said head, the guides H, the knife-guides K K, one upon each side of the knives, the cuttingblock M beneath said knives, the hooprest N on said block, the centering-guides O P on said rest, and the stop L, all arranged substantially as described.

In testimony whereof I affix my signature in presence of two witnesses this 13th day of October, 1887.

OTTO SGHIMANSKY.
